Positive effects of HIIT and vitamin E on cognitive function, angiogenesis and NRF2 antioxidant pathway in male rats with Alzheimer's disease.
Article in Biogerontology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Interactive effects of exercise and antioxidant supplements are still not well known. So, The aim of this study was to investigate the effects of high intensity interval training (HIIT) and vitamin E (VE) on the PI3K/NRF2 pathway in the hippocampus of Alzheimer's disease rats (AD). In this expremantal study, fifty aged AD rats with 10 mg/kg trimethyltin (TMT), were divided into groups 1) TMT, 2) VE solvent (Sham), 3) VE (30 mg/kg), 4) HIIT (90-95% of the maximum running speed) and 5) HIIT+VE. Ten healthy rats were included in the healthy control group to investigate the effect of TMT on research variables. Results Showed that, HIIT, VE and HIIT+VE decreased amyloid beta (P≤0.05), HIIT and HIIT+VE decreased NF-kB (P≤0.05) as well as HIIT, VE and HIIT+VE increased SOD and decreased MDA. HIIT simultaneously with VE increased PI3K, NRF2, and Cat. HIIT, VE and the interaction of HIIT and VE decreased the expression of miR-125b and increased expression of miR-132 (P≤0.05); The combination of HIIT and VE increased capillary density in areas 1 and 3, the percentage of healthy cells in C1 and C3 areas of the hippocampus (P≤0.05). The effects of HIIT and HIIT+VE on improving memory were better than VE (P≤0.05). It seems that HIIT and VE can synergistically increase the expression of antioxidant genes from the PI3K/NRF2 pathway by decreasing miR-125 and increasing miR-132. Probably, this happens by reducing some AD markers, increasing angiogenesis and cell protection as well as cognitive memory in AD situation.
